Playing with fuzzers

[Emiel Kollof]

Hi,

Ilja van Sprundel (some of you might know him) was playing around with a 
trivial syscall fuzzer in DragonFly 1.6-RELEASE and found a few bugs. 

One is a free(NULL) in sendmsg, and a panic in malloc that's triggered by 
vfork -> fork1 -> fdcopy -> malloc.

His fuzzer is available here: http://www.digitaldwarf.be/products/sysfuzz.c

The ignore-list that's custom for DragonFlyBSD is:

int ignore[] = 
{1,2,29,119,113,120,173,72,162,91,82,251,240,346,341,74,345,322,8,73};

Might be a nice idea to fuzz syscalls and fix bugs. 

Cheers,
Emiel
